سابقه و هدف: از آنجا که توافق کلی درباره بهترین روش ارزیابی ختم حاملگی در سه ماهه اول با میزوپروستول وجود ندارد، مطالعه حاضر به منظور مقایسه سونوگرافی و β hCG در ارزیابی کامل بودن سقط در بیماران بستری شده در بیمارستان شبیه خوانی کاشان در سال 1389 انجام شد. مواد و روش ها: در این مطالعه 133 بیمار که سقط فراموش شده داشته یا تخمک پوچ آنها با استفاده از سونوگرافی تایید گردیده و ساک حاملگی آنان حداکث...
The placenta may be involved in the regulation of the maternal thyroid function during pregnancy. As human chorionic gonadotropin (hCG) is a primary protein from the placenta, we examined the thyrotropic activity of hCG and its derivatives using tissue culture and monolayer cell culture of human thyroid glands. The TSH receptor preparation was made from thyroid tissues, and its binding affinity...
Trisomy 21 is associated with high maternal serum concentrations of intact human chorionic gonadotrophin alpha(HCG) and free beta-HCG whereas these concentrations are markedly decreased in trisomy 18. In this study, we investigated the effect of trisomy 21 and 18 on endogenous HCG concentrations and luteinizing hormone (LH)/HCG receptor expression in placental villous tissue in eight trisomy 21...
Human chorionic gonadotropin (hCG) is a glycoprotein hormone comprising 2 subunits, alpha and beta joined non covalently. While similar in structure to luteinizing hormone (LH), hCG exists in multiple hormonal and non-endocrine agents, rather than as a single molecule like LH and the other glycoprotein hormones. These are regular hCG, hyperglycosylated hCG and the free beta-subunit of hyperglyc...
Aim. To analyse the levels of serum beta-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein A (PAPP-A) in pregnant women without fetal chromosomal abnormalities with trisomy 21 (Down syndrome) or 18 (Edwards syndrome). Materials Methods. We performed a retrospective analysis biochemical parameters 1214 who had previously undergone karyotyping as part prenatal postnatal...
Vertical-cavity surface-emitting lasers (VCSELs) have been widely used in consumer electronics, light detection and ranging, optical interconnects, atomic sensors, so on. In this paper, a VCSEL with the surface metastructure like one-dimensional high-contrast grating (HCG), based on HCG-DBR vertical cavity, was first designed fabricated. The polarization characteristic of HCG-VCSEL were experim...
BACKGROUND hCG is a wonder. Firstly, because hCG is such an extreme molecule. hCG is the most acidic glycoprotein containing the highest proportion of sugars. Secondly, hCG exists in 5 common forms. Finally, it has so many functions ranging from control of human pregnancy to human cancer. This review examines these molecules in detail. CONTENT These 5 molecules, hCG, sulfated hCG, hyperglycos...
Aim Outside of Japan, recombinant-human chorionic gonadotropin (r-hCG) is widely used for the induction of final follicular maturation and early luteinization in women undergoing ovulation induction; whereas in Japan, urine-derived hCG (u-hCG) is predominantly used. The primary objective of this study was to demonstrate the non-inferiority of r-hCG to u-hCG for ovulation induction, as assessed ...
Purpose Recombinant hCG (r-hCG) was approved in Japan in 2016. As a prerequisite for a Phase III study in Japan related to this approval, the pharmacokinetic (PK) profile of r-hCG was investigated. Methods An open-label, partly randomized, single-center, single-dose, group-comparison, Phase I PK-bridging study was done that compared a single 250 μg dose of r-hCG with a single 5000 IU dose of ...
در این مطالعه اثرات تزریق هورمون¬های اواپریم،hcg و عصاره هیپوفیز بر پارامترهای بیوشیمیایی پلاسمای اسپرمی مولدین نر ماهی سفیدک سیستان (schizothorax zarudnyi) مورد بررسی قرار گرفت. به این منظور، تعداد 20 مولد نر ماهی شیزوتوراکس تحت تزریق چهار نوع القاء کننده شامل هیپوفیز (mg/kg 2/0)؛ اواپریم (ml/kg 3/0)؛ hcg (iu/kg 400) و سرم فیزیولوژی (ml/kg 3/0) به عنوان شاهد در 5 تکرار به ازای هر تیمار قرار گر...
